Aviation regulator DGCA announced it de-registered seven Boeing 737-800 aircraft of Jet Airways on Wednesday, allowing its lessors to take the planes out of the country so that it can be leased to any other airline.

During the last a few weeks, Jet Airways has been grounding its aircraft in tranches due to non-payment of dues to its lessors. While the airline has a fleet of about 119 aircraft, Civil Aviation Secretary Pradeep Singh Kharola said on April 4 that only 26 aircraft of Jet Airways are flying "currently".

All aforementioned seven companies are based out of Dublin in Ireland. They had put in the IDERA (irrevocable deregistration and export request authorisations) requests with the DGCA on and around April 3.

The regulator also showed on its website that lessors have put in IDERA requests to de-register 24 other aircraft, which were leased to Jet Airways.

Once the lessor puts in the IDERA request for an aircraft, the DGCA checks if that plane has any pending dues with any airport, oil companies, etc. Once it is established that plane has no pending dues, the de-registration is permitted. The lessor can then take the plane out of the country and lease it to any other airline company.

Meanwhile, a European cargo services provider seized one of Jet Airways' Boeing planes at the Amsterdam airport for non-payment of dues on Wednesday.

Also, for the third time in a week, national oil marketer Indian Oil on Wednesday stopped fuel supply to Jet Airways for non-payment of dues.

Due to cash crunch, the airline has been paying only part salaries to its over 16,000 employees which forced a section of its pilots on Tuesday to send a legal notice to the management, which is currently being headed by the lenders led by the State Bank of India.
